Four candidates - two boys named Patrick and Quincy, and two girls named Rhonda and Sally - ran for student body president. By the rules, the candidate who wins more than half the ballots cast wins the election outright; if no candidate wins more than half, there must be a runoff between the two top vote-getters. You may assume that no other names were written in.
As can be seen in the figure above, which reflects the share of the vote each candidate won, there will be a runoff. Which two candidates will face each other?
Statement 1: Candidates A and B are both girls.
Statement 2: Candidate B and C are Rhonda and Patrick, respectively.

Candidates A and B are the top two vote-getters, so we must establish which two candidates are A and B.
Statement 1 does just that by identifying them as Rhonda and Sally. It does not identify which one is which, but it is not necessary to know that.
Statement 2 identifies Rhonda as Candidate B, but only Patrick can be eliminated as Candidate A.

Each statement alone gives information about only one order, so at the very least, both statements will be necessary.
From Statement 1, it is known that Ralph will pay 
for his drinks, since he will only pay for the two espressos.
From Statement 2, it cannot be determined exactly what Janet will pay. However, she will pay for all three drinks, two of which are cappucinos; the least she will spend is the price of two cappucinos and an Americano, which is

Below are the results of the initial election for senior class president.
No candidate won a majority, so Crane and Trask faced each other in a runoff. Every student in the senior class voted in both the initial election and the runoff. Every student who voted for Crane in the initial election voted for Crane in the runoff, and every student who voted for Trask in the initial election voted for Trask in the runoff.
Who got the most votes in the runoff, Crane or Trask?
Statement 1: All of the students who voted for Jones in the initial election voted for Crane.
Statement 2: Two-thirds of the students who voted for Wells in the initial election voted for Trask.

From Statement 1 alone it can be determined that Crane won at least

From Statement 2 alone, it can be determined that Crane won at least

Neither statement alone will prove a majority vote. From Statement 1 and 2 together, however, it is known that Crane won at least his own initial votes, all of Jones' votes, and one-third of Wells' votes - a minimum of

Assume both statements to be true. Anya is Candidate C. Candidate D, being neither Barry nor Carla, is David. Therefore, Candidates A and B are Barry and Carla; it is unclear which is which, but it is irrelevant; either way, they are the top two vote-getters, and they will participate in the runoff.
Four candidates - two boys named Mickey and Oswald, and two girls named Nora and Phyllis - ran for student body president. By the rules, the candidate who wins more than half the ballots cast wins the election outright; if no candidate wins more than half, there must be a runoff between the two top vote-getters. You may assume that no other names were written in.
As can be seen in the figure above, which reflects the share of the vote each candidate won, there will be a runoff. Which two candidates will face each other?
Statement 1: Nora is candidate B and Oswald is Candidate C.
Statement 2: Candidates A and C are boys.

Candidates A and B are the top two vote-getters, so we must establish which two candidates are A and B.
Statement 1 alone establishes that Nora is Candidate B, making her one of the top two vote-getters. Oswald is not one of the top two, since he is Candidate C, but neither Mickey nor Phyllis can be eliminated as Candidate A.
Statement 2 alone established that one boy is Candidate A, one of the top two vote-getters. Since the other boy is Candidate C, then the other one of the top two, Candidate B, is a girl. However, it does not establish the identity of any of them.
Now, assume both statements to be true. By Statement 2, the top two are a boy and a girl. Statement 1 establishes that the girl is Nora. Since Statement 1 also establishes that Oswald is not the boy, the boy is Mickey, and it follows that Mickey and Nora will face each other in the runoff.

Statement 2 identifies Rhonda as Candidate B, but only Patrick can be eliminated as Candidate A.

Each statement alone gives information about only one order, so at the very least, both statements will be necessary.
From Statement 1, it is known that Ralph will pay for his drinks, since he will only pay for the two espressos.
From Statement 2, it cannot be determined exactly what Janet will pay. However, she will pay for all three drinks, two of which are cappucinos; the least she will spend is the price of two cappucinos and an Americano, which is .
